To all whom it may concern:

Be it known that we, SAMUEL Gr. Goes, s

citizen of the United States, of Glencoe, in the county of of Illinois, and

and e resident Cook and State Enxns'r JAMES SMITH, a subjeot of the King of England, and a resident of Chis-ego in the county of Cook and State 01" Illinois,

have invented certain new and useful Improvements in Wehltoll Mechanisms for Printing-Presses, of following is a specification,

which the reiei'ence being had to the accompanying di'swings.

Our invention relates to web roll meshenisms for printing presses or other web meohines, and it has for its principal object the provision of new and improved means for changing from one web without stopping the press Without slowing down the Our improved eonsti'uction is of the et forth in tion.

general type s Samuel G. GOES,

roll to another and preferably speed of opera the sppliostion of Sexual No, 131,159, and we do not desire to claim by on? application the subject-matter shown, described and by the said prior application. tion comprises a frame two rolls of paper,

claimed Gui invenedeggzted to support endless tape belts by which the web from either of said rolls is led to the press, means for setting s fresh roll into rotation 1n either position at substantially the same speed as that of the web running to the press from the other roll,

and means for carrying the web from the fresh roll into contact with the web running from the other soil as the former web un winds upon the rotation of the fresh roll.

it is one of the especial objects of our in.- vention to provide new and improved means for carrying the end of the web of the fresh roll into Contact with the running web. lt

Fig. l is a fragmentary View taken substantially at line of Fig. 1 also at the far side of the mechanism shown in said Fig. 1.

Referring to the several figures of the drawings, in whichcorresponding are indicated by the same reference characters-- 10 indicates a frame located in a (lOillPlililment or room helow that in which a printing press 01 other web machine is located. lleb IOllS 1l-.l2 are suppoited by spindles l3ll, respectively, mounted in suitable hearings l5l supported in suitable position upon horizontally-extendiug arms 17* The web 19 from the Web roll 12 in use, as shown in 1, extends upward from the roll and over it roller 20 which is ievoiubly mounted upon s shaft 21 which in turn is yieldingly n'iounted upon thefi'ame 10. The web extends from the roller 20 between two rollers 22-23 which are mounted by means of she-its 2%25, respeotively, upon the fi'aine 10 in close proximity to each other, being adapted to feed a web or webs forward between them. The web extends to the left from the rollers 2223 between endless tape belts 26-27 dition by means of sheaves. or pulleys 28 upon shafts 29, and 31. The upper end portions of the endless tape helts226-2l ere not shown, but it will be understood that such belts are to be driven l y suitable e1- rsngement of supporting and driving means upon the press or othe web machine with which the web 12* is to he used, the belts 26?! being e the same surface speed as that of ii The shafts 29 and 36 site also prov deli with roller sections 32 between the sheaves 58 for holding the web in proper smooth condition. A shai'ft33 is 'ielding ly mounted upon the lysine 10 immediately shove shaft 21, supporting in position e roller 3% about which the welo from the roll the upper nosition is adeptedto pass and from which such web extends to the rollers 22-23.

The rollers 20 and 34 are formed in sections to permit of sheaves or pulleys 35 being mounted upon the shafts 21-33, as is best shown in Figs. 2 and 3. The rollers and 23 are also formed in sections to permit of sheaves or pulleys 36 being mounted upon the shafts 24-25 in alincment with. the sheaves or pulleys 35. 'lransversely-ext'ending shafts 37-38 are provided with sheaves 0r pulleys 39-40, respectively, in alinement with the sheaves or pulleys 35-36. Tapes 41 secured. to the sheaves or pulleys 39 extend under the sheaves or pulleys 36, from thence about the sheaves or pulleys 35, and from thence to the sheaves or pulleys 40 to which they are secured, the tapes 41 being adapted to be reciprocated between the sheaves 39 and 40 by "belng wound alternately upon one or the other set of such sheaves. Transverselyextending shafts 42-43 are likewise provided with sheaves or pulleys 44-45, respectively, in alinement with the sheaves 35-36 upon the shafts 21-25. Tapes 46 secured to the sheaves or pulleys 44 extend from such pulleys over the sheaves or pulleys 36 upon the shaft 35, and from thence about the sheaves or pulleys 36 upon the shaft 21 to the sheaves 45 to which they are connected,. the tapes 46 being adapted to be moved back,

and forth from one to the other of the shafts 42 and 43, being wound upon one or the other of the set of sheaves 44-45. Each of the shafts 37, 38, 42 and 43 is provided with a spiral spring 48 which resists turning of the shaft relative to the frame 10. Each of the springs 48 is so mounted as to have a tendency to turn its shaft in the direction to wind the tapes 41-46 upon the sheaves mounted on that shaft,that is to say, the springs upon the shafts 37-42 oppose the springs upon the shafts 38-43. The springs upon the shafts 37-42 are stronger, however, whereby the tapes 41-46 are adapted to be wound upon the sheaves 39-44 against the action of the springs upon the shafts 38-43 whenever the tapes are released for free movement. The shafts 38-43 are adapted tobwlo-cked against rotation in the direction 'tp nnwind the tapes from the sheaves 40-45, this result being attained by the use of pawls 49 'pivotally mounted upon the framelO and cooperating with notched collars 50 upon the shafts 38-43. The shafts 38-43 are adapted to be rotlated in the direction to wind the tapes 41-46 upon or pulleys 40 by a pull upon the cord 51, this result being attained against the action of for holding the tapes 41 against movement toward the left in Fig. 1. The end of the web of the roll 11 is then secured lightly in position upon the tapes 4'1 by any suitable means strong enough to resist the effective pull of the springs 48 u on the shaft 37 but at the same time easily releasable at the proper moment. Such a connection may readily be effected by theuse of pins or small paper stickers or pastors, as will be readily understood. When the end of the web has been secured to the several tapes 41, the pawl 4956s turned out of engagement with the notched collar 50, whereupon the spring 48 on the shaft 37 exerts a constant pull. upon the web of the fresh roll, but not such a pull as is adapted to rotate the roll 11 for unwinding the web therefrom. lVhen the web is substantially exhausted from the roll 12, a layer of adhesive material is applied to the end of the web of the fresh roll, whereupon the parts are in readiness for the operation of splicing the end of the fresh web to the web running from the roll 12 whenever by any suitable means the roll 11 is given a rotation in clockwise direction in Fig. 1.

It will be understood that when the roll 11 becomes substantially exhausted a fresh roll is inserted upon the spindle 14, and the parts are prepared for the splicing operation in the manner above described in connection with the fresh roll upon the spindle 13, the end of the web of the fresh roll in the lower position being secured to the tapes46 rather than to the tapes 41.

The means which we have provided for rotating a fresh roll in either of the two positions in the frame 10 and forbringing the rotation of the first roll very quickly to the same surface speed as that of the web running from the roll in the other position, comprises ashaft 53 which 18 driven by any suitable mechanism from the press or other web machine. The shaft 53 is provlded with the beveled gear 54 which meshes with a beveled gear 55 fixed upon the end'of a shaft 56 which is connected by means of gears 57-58 with sleeves 59 revolubly mounted upon a'i'rock-shaft 60 extending across the frame below the shaft 56. The

slecves 59 have fixedly inpuntedthereon sheaves or pnlleystil about which extend endlesshelts 62, the upper ends of which are supportedxby sheaves or pulleys 63 whlch are revolubly mounted between arms 64-65.

The arms 65 are swingingly mounted at their lower ends about the sleeves 59,-While the arms 64 are fixedly connected at their lower ends with the rock-shaft 60. The belts 62 are thus adapted to be driven continuously through the shaft 56, the gears 5'a'-58 and the sleeves 59, and the belts 62 are adapted to be swungabout the axis of the roclr-slnnt (it) by reason of the fixed connection between the arms 6% and said rockshaft. The rock-shaft (S0, is adapted to be given a limited rotation in either direction y means of a segmental gear cc, fixed upon the end of said shaft, meshing with another segmental gear 67 revolubly mounted upon the frame 10 and provided with a handle or lever 68 for turning it.

The shaft 53 is provided at its lower end with another beveled gear 69 meshing with a beveled gear 70 mounted upon a shaft 71 which is connected by means of gears 72-73 with sleeves 7 lrevolubly mounted upon a shatt'io. The sleeves 74 are provided with sheaves 76 which support the upper ends of endless belts 77, the lower ends oil which pass about sheaves 78 revolubly mounted between arms 798O depending from the rock shaft 75. The upper ends of the arms 80 are revolubly mounted about the sleeves 74, but the upper ends of the arms '79 are fixedly mounted upon the shaft 75, the belts being thus adapted to be swung about the shaft 75, while being free to be driven by the shaft 71. The shaft 75 is provided at its outer end with a segmental gear 81 which meshes with the gear 87.

The shaft 53 driver; constantly at such a speed as to cause the belts 6&4? to have thesarne surface speed as that of the web running to the press or other web machine. When a fresh roll in the upper position is to be substituted for the substantially exhausted roll in the lower position, when the parts have been all prepared for the change as above described, the lever 68 is given a sharp upward movement, bringing the belt 62 into contact with the periphery'of the upper roll, serving to set such roll very quickly into rotation at the same surface speed that of the web running from the lower roll. The spring 48 upon the shaft 3'? serves to draw the tapes 41 toward the left in Fig. l as rotation of the roll 11 proceeds. t will he understood that in practice the distance be tween the shafts 33 and 2 will be such that by the time tilna of the web of the fresh roll has been curried by the tapes ll from its position adjacent to the shaft 33 into the bite of the rollers 25Z-23, the roll 11 will have assumed its full speed rotation at the desired surface speed. l-Vhen the gummed end of the Web of the fresh roll is brought into contact with the running web between rollers it is pressal firmly against such web and thus fixedly secured tln-areto. As the end of the fresh web passes the roller 22, the means by which the end of the web is secured to the tapes i1 are released, by reason of the fact that the connection of the fresh web to the old web by means of the gum is very much stronger than the connection of the fresh web to the tapes. When the end of the fresh web has passed beyond the rollers '22-23 and has thus been secured firmly to the running web, a blade 82 is given a. downward movement about the shaft 83 upon which it is swingingly mounted for severing the old web. in the construction shown the shaft 83 of the severing blade 82 is swung by means of a head 84 which is adagited to be turned in either direction as desired by means of cords 8586 attach .d t: its opposite sides.

in the construction shown the tapes 4146 are separtcd by a suflicient space be tween the rollers 22 and 23 so as to permit such tapes to be moved. to the right in Fig. 1 without interfering with the movement of the running Web at the same time toward the left in said figure.

As will be readily understood, when a fresh roll in the lower position is to be substituted for a substantially exhausted roll in the upper position, the lever 68 will be swung sharply downward, instead of uplva-rd as above described, for bringing; the the bolts 77 into contact with the roll in the lower position for setting it into rotation at the desired speed.
